Lamp Fault Code (LFC)

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

When the Restraints Control Module (RCM) detects a system fault, it will flash a coded sequence which is called a Lamp Fault Code (LFC) on the air bag warning indicator located in the Instrument Cluster (IC) module. The code is 2 digits. The first digit is flashed with a 0.5-second interval between pulses. There is a 2-second pause before the second digit is flashed, which also has a 0.5-second interval between pulses. There is a 5-second pause between each display of an LFC.

Each LFC is flashed 3 times after which the air bag indictor will remain lit for the remainder of the key-on cycle (except for DTC B2792 [cross link between firing loops] which only flashes one LFC). If there are multiple LFCs, each LFC will flash in order of priority.
